Random Sphere

This sphere will give you a “random” one of the Soulsphere, Megasphere, Blursphere, and the Skulltag spheres above. In reality, the sphere given is not random, but whichever one was displaying when the player picked up the Random Powerup. The spheres always cycle in the same order, so a nimble player can choose whichever sphere he wants.

Level makers can specify exactly which spheres are available from a Random Powerup by setting its first argument as follows:

1    Megasphere
2    Soulsphere
4    Guardsphere
8    Blursphere
16   Timefreeze
32   Invisibility
64   Doomsphere
128  Turbosphere

Add up the number for each sphere you wish to allow; for example, a first argument of 11 will make the Random Powerup cycle through Megasphere, Soulsphere, and Blursphere, but none of the Skulltag spheres. For convenience, however, an argument of 0 enables all spheres rather than none.

Permanent quad damage "Until you die"
Full health and armour (200/200%)
Earn 10 frags for killing a Player that is a Terminator

Hellstone

When you pick up the HellStone you will:

Lose all of your weapons
Not able to defend yourself
Try not to be killed!

After the timer on the top of the screen runs out while you are holding the HellStone, you will win a point!
